SMOKING PIPE.

Application led October 30, 1923. i Serial No. $71,683.

This invention relates to smoking pipes and is particularly directed tomeans for securing improved smoking qualities.

Pursuant to the invention, the smoking 6 pipe includingr the usual bowlhaving a stem portion and a separable stemportion carrying the mouthpiece. is combined with a member for eifectually removing nicotine rother moisture orsaliva and dust whereby lothere is afforded acontinuously `maintained clear passage through the bore of the pipe stemfor the smoke developed upon ignition of the tobacco in the bow Pursuantto the more preferred forms 1 5 of my invention, such removal of thetobacco dust, saliva, nicotine or other moisture and other products ofcondensation resulting in the use of the pipe in smoking, is eifected bymeans of a member of non-ignitible material such as metal and shapedspirally or of other nonuniplanar configuration whereby such nicotine orother moisture, dust and the like which are developed upon ignition ofthe tobacco in the bowl and carried upon inhalation by the smoker intothe -pipe stem, are eteetually impeded and retained at distributedlocations within the bore of the stem and effectively out of the path ofthe smoke. 'In a similar manner,

such provision of means, in the event of saliva entering the mouthpiece, directs and retains the same at a similar location, out ofeffective intercept with the smoke passing through the pipe bore.

Such dust and nicotine or other moisture separating means serves also asa means for thoroughly cleansing the bore of the pipe, by manualwithdrawal of the spiral means through the bore, as by removal of thesep- 0 arable portion of the stem from the bowl portion of the stem in aseparable type of pipe, whereby upon manual withdrawal of the spiral orequivalent member outwardly V:from the pipe stern, the dust and nicotineor other moisture are transferredL exteriorly of the bore.

Further features and objects of the invention will be more fullyunderstood from the following detail description and the accom 30panying drawings, in which Fig. l is a vertical central sectional Viewthrough the bowl and stem of a pipe, of the form in. which the stem isseparable substantially at its center;

Referring to Figs. 1 to 6, inclusive, the pipe per se may be of anyapproved or desired form and general construction, and comprising thebowl 11, the stem portion 12, usually permanently secured to the bowl11, and the separable stem portion 13, at the outer end 14 of which isthe mouth piece, either permanently `or removably carried thereby. Suchseparable feature for the stem portions 12, 13 may be provided by meansof the reduced stem portion 15 projecting from 'the inner end of thestem portion 13 and secured by frictional fit within the recess 16 atthe outer end of the bowl stem portion 12.

Within the bore 17 of the pipe stem 12--13 is disposed, pursuant to myinvention, a 95 twisted or spirally coiled member 18 of aluminum or likesufficiently stiff and preferably non-corrosive material suitable forthe purposes desired. Such member 18 is preferably of a lengthcorresponding to the 100 length of the bore 17 from the mouth piece 14to a location 19 in advanceof the center oi the bowl 11, in whichcircumstance the inner end 2O of the member 18 is provided with anenlarged opening 21, see Fig. 2, or 105 slot or equivalent, whereby anenlarged effective free clearance is provided for the draft from thebottom of the bowl 11 into the stem bore 17.

Upon filling the bowl with tobacco, with n.

modification,

on a greatly the stem and the dust and nicotine or other moisture memberassembled, as indicated in Fig. l, upon inspiration by the smoker, thesmoke is drawn through the bottom of the bowl, thence into contact withthe member 18, including a considerable portion of the smoke passingthrough the slotted opening 21, the path' of the smoke then continuingabout the passage afforded between 'the various portions of the member18 and the wall of the bore 17 of the pipe, whereby the smoke is given amore or less centrifugal movement. The condensed nicotine. or othermoisture resulting from the ignition of the tobacco, gravitates towardthe bottom of the bore 17 and will be distributed intime on the bottomof the bore from the bottom of the bowl toward the mouth piece.centrifugal movement of the smoke, carrying any dust or other substanceforeign to the smoke, is whirled into contact with such Acondensednicotine or other moisture and thereby entrapped. Similarly, in theevent of saliva entering the opening of the mouth piece 14, is broughttoward the bottom of the bore and operates to catch dust and the like.

Such action is enhanced by providing an effective diameter of the member18 substantially that of the bore 17 of the stem.

Such member 18 is also referably provided with suitable means or lodgingthe same withinl the bore 17 of the pipe stem, as by providing themember 18 with the spaced lugs 22, 23' for retaining the member 18relativeto the reduced stem portion 15. As is indicated in Figs. 3, 4, 5and 6, the reduced portion 15 may be provided with the correspondinglyspaced re-entrant recesses 24, 25, arranged to respectively receive theretaining lugs 22, 23 and forming therewith a bayonet joint, wherebyupon withdrawal of the separable stem portion 18, the member 18 issimultaneously withdrawn through the stem portion 12, but retained bythe above described vsupport for the member 18 within the removable stemportion 13.

Such withdrawal of the member 18 through the bore of the stem portion 12eects a displacement of the edge portion of the member 18 longitudinallyalong and against the wall of the bore and thus producing a scrapingaction, and removing dust, nicotine or other moisture and the liketherefrom. Such withdrawal action may be repeated as often as desired.

Upon disconnecting the member 18 from the separable stem portion 18, andwithdrawing the same through the bore thereof, a similar removal actionis effected for the dust, nicotine or other moisture from the bore ofthe stem portion 13.

In Fig. 3, the member 18 is shown lodged with its retaining lugs 22, 23respectively in Such the bayonet slots 24, 25 and the effectual diameterof the spiral member 18 substantially that of the bore 17, that is tosay, to make an easy fit therein.

In Fig. 7, the opening 30 at the inner end of the 'member 18 is shownsomewhat enlarged along the length of the member 18.

If desired, and as indicated in Fig. 8, the member 31, corresponding tothe aforesaid member 18 may be provided with the openings 32, 32adjacent the opposite ends of the member 81, whereby the opening 32located adjacent vthe opening of the mouth piece 14 when positionedwithin the ipe, may be employed to receive the end o the match, toothpick, button` hook, bent Wire or the like, to afford withdrawal of themember 31 from the 'bore' of" the pipe. ASuch form of the invention maybe employed in pipesy of the separable stem type, as indicated in Fig.1, or with ipes having a stem integr-al throughout its length.

From the above,'it will be erceived, as I have discovered from actua useof my invention, substantially all the nicotine, moisture and otherwater content of the gases resulting from combination of the tobacco,are automatically entrapped and retained within the bore' of the ipewhile sufficient full assage is provi ed at all times for the ree draftthrough the pipe bore. The smoking derived by means of a pipe having minvention, is cool and without any bite, and allows such pleasurablesmoking for a comparatively long period of use, and particularly forrelatively long periods of continuous use.

The invention also provides for read removal of thegiicotine, dust andthe like rom the bore without the necessity of having any auxiliarydevice, such as a. pipe cleaner, and the cleansing is readily effectedwithout soiling the hands of the user, as the cleaner member may begrasped by a piece of newspaper or cloth or the like and cleansed.

The configuration of the member 18 may be varied, as by twisting a metalstrip irregularly, as distinguished from the regular spiral as isillustrated in Figs. 1 and 8, while retaining the essential features ofthe provision of a whirling path for the smoke through the bore, aplurality of edge 0r other portions of the body of the member in spacedcontact with the walls of the bore and suitability for grasping one endthereof for facilitating its withdrawal from the bore.. In Figs. 9 and10, I have illustrated a helically coiled member 38, and referably of atriangular or other polygonalpcross-section, to provide spaced edge orrelatively sharp portions for engagement with the walls of the bore ofthe pipe stem.

lVhereas I have described my invention by reference to specific formsthereof, it will be understood that many changes and modiiioations maybe made without departing slots, a spirally arranged member disposedfrom the spirit of the invention. in the bore ofsaid bowl stem portionand I claimthe bore of said mouth piece stem portion 15 The combinationof a pipe comprising a said spiral member engaging the walls o 5 bowlportion, a bowl stern portion, a bored said bores at'spirally continuouslocations, mouth piece stem portion and means for a set of lugs carriedby and projecting from disconneotably connecting said mouth piece saidspiral membeiI and removably received stem portion with said bowl stemportion, Within said set ofbayonet slots.' i0 said connecting meanscomprising a tubular In testimony whereof I have signed this 10 .membersecured to and projecting from said specification this 26th day ofOctober, 1923.
